is it time to look at the weapon enchant transmogs? with the exception of maybe 3 (winter’s grasp, Blood draining and power torrent), most enchants effects are greatly reduced with most weapons, and often slightly reduced on those 3 listed above
obviously as weapons become more flashy, old enchants are not showing as distinctly, but even on maybe the most plain sword i could find i had as an example, “sword of Serenity” some like “Striking” and “Agility” are not showing a noticeable effect!!! so, depending on your background, your enchant might not show through!
the easiest suggestion in my mind, would just to be to make the effect stronger. i would love a strong “netherflame” for example, but its just not strong enough to show on some more detailed, or larger weapons as i think some of these enchants seem to start from a uniform point from the center of a model, and the larger of a model a weapon has, the less of the enchants glow will be shown. i may be wrong on this point, but its either this, or again the glow is just not showing on newer weapons, even if they are not fancy glowy weapons as standard.
